Chemical Structure

Pentamethylbromobenzene CAS 5153-40-2 chemical structure

Description

As a certified reference material (CRM), Pentamethylbromobenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Pentamethylbromobenzene (CAS 5153-40-2), a certified reference material (molecular formula C11H15Br, MW 227.14 g/mol) for analytical method development and quality control.

Pentamethylbromobenzene (C11H15Br) contains bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
